Division sheet



Nov. 8, 1932. s. B. FREIBERG DIVISION SHEET Filed Dec. 16. 1950 Patented Nov. 8, 1932 UNITED STATES PATENT o F c STANLEY IB. FREIBERG, or CINCINNATI, orIIo, AssIGNoR TO THE INTERNATIONAL VISIBLE SYSTEMS CORPORATION, or oINoINNA'rI, OHIO, A oonronArlon or- OHIO DIVISION SHEET Application filed December 16, 1930. Serial. No. 502,691.

This invention relates to improvements in division sheets of the character shown in my copending application, Serial Number 432,467, filed March 1, 1930.

An object of this invention is to obviate the difficulties encountered incident to the folding or the breaking down of the corners of division sheets such as are shown in my said copending application, and at which corners the division sheets are mounted upon prongs of binders.

Another object of the invention is to provide a simple structure that will obviate the difiiculties incident to the breaking down of the corners of division sheets adjacent the prongs carrying such division sheets.

These and other objects are attained by the means described herein and disclosed in the accompanying drawing, in which:

Fig. 1 is a fragmental plan view of a binder in which is mounted a division sheet embodying the invention.

Fig. 2 is a sectional View taken longitudinally of a division sheet embodying the invention.

The division sheet 10 is made of a suitable material such as paper, fabric, card board, fibre, or the like, and is provided along its one longitudinal edge with a plurality of apertures 11, through which the various prongs 12 of the binder 13 may extend. Along the upper and lower transverse portions of the sheet 10 are mounted suitable pad or filler members 14 that may be of cork or of any other suitable material. The specific substance used for a pad or filler member is immaterial. That edge portion of the filler sheet containing the row of perforations is cut away at the upper and lower portions as indicated at 15 and 16, thereby eliminating any material that might otherwise be damaged and by reason of its having become damaged, interfere with the proper manipulation of the various record sheets disposed along the upper and lower margins of the border. Likewise, there is no hindrance to the ready manipulation of the division sheets themselves.

Inasmuch as division sheets of the character under consideration comprise pads 14 that are thicker at the upper and lower edges of the'division sheet than they are toward'the center of the division sheet, the heavier material that heretofore was received by the endmost prongs, interfering with free and ready manipulation of the division sheets, does not, in my improved form, contact to impede manipulation of the improved division sheet.

In the preferred form of filler sheet, the pads 14 extend outwardly from adjacent the edges of the perforations 11 to the free edge 17 of the sheet 10. The pads 14 do not, in the preferred form, extend quite to the perforations 11, there being a small space betweenthe lateral edges 18 of the pads and the perforations 11.

The lateral edge 19 of the sheet is shaped like an index tab, such as is provided on various types of index cards. This tablike formation results from cutting away elongated portions at the opposite corners of the rear edge of the sheet, the elongated recesses or cutouts extending in alignment with the row of perforations 11, or longitudinally of the sheet.

What is claimed is:

1. A rectangular division sheet having a row of perforations along its one lateral edge, a filler pad carried at each of the upper and lower edges of the sheet and lying between the row of perforations and the opposite lateral edge of the sheet, the perforated lateral edge of the sheet being shorter than the opposite lateral edge of the sheet and terminating inwardly from the upper and lower edges of the sheet, whereby the perforated edge of the sheet assumes a perforated tab-like formation along one lateral edge of the sheet.

2. The combination with a binder comprising a plurality of parallel prongs spaced at intervals along the binder, and a plurality of overlapping record sheets mounted on the prongs, of a division member comprising a sheet having a row of perforations along its rear lateral edge and through various of which perforations the prongs extend, the perforated sheet edge terminating between the upper and lower binder prongs whereby to provide retracted corners relative said upper and lower binder prongs and to obviate impaling of the sheet by said upper and lower prongs, and filler pads on the sheet and extending from the retracted sheet corners to the forward lateral edge of the sheet and covering areas at the upper and lower portions of the sheets.

3. A division sheet having a row of perforations along an edge, the corners of said edge being cut away to provide a tab-like formation along said edge, and filler material carried by the sheet and extending across the sheet from said tab-like formation and'being substantially co-extensive with the end portions of the sheet adjacent said cut away corners thereof.

In testimony whereof, I have hereunto subscribed my name this 8th day ofDecember, 1930.
